BACKGROUND OF THE INVENTION

1. Technical Field of the Invention

This invention relates generally to communication devices and more particularly to the communication devices that communicate with multiple networks in multiple frequency bands.

2. Description of Related Art

Wireless communication systems are known to support wireless communications between wireless communication devices affiliated with the system. Such wireless communication systems range from national and/or international cellular telephone systems to point-to-point in-home wireless networks. Each type of wireless communication system is constructed, and hence operates, in accordance with one or more standards. Such wireless communication standards include, but are not limited to IEEE 802.11, 802.15, 802.16, long term evolution (LTE), Bluetooth, advanced mobile phone services (AMPS), digital AMPS, global system for mobile communications (GSM), code division multiple access (CDMA), wireless application protocols (WAP), local multi-point distribution services (LMDS), multi-channel multi-point distribution systems (MMDS), and/or variations thereof.

An IEEE 802.11 compliant wireless communication system includes a plurality of client devices (e.g., laptops, personal computers, personal digital assistants, etc., coupled to a station) that communicate over a wireless link with one or more access points. As is also generally understood in the art, many wireless communications systems employ a carrier-sense multiple access (CSMA) protocol that allows multiple communication devices to share the same radio spectrum. Before a wireless communication device transmits, it “listens” to the wireless link to determine if the spectrum is in use by another station to avoid a potential data collision. In other systems, transmissions can be scheduled using management frames or power save multi-poll (PSMP), for example. In many cases, the transmitting device (e.g., a client device or access point) transmits at a fixed power level regardless of the distance between the transmitting device and a targeted device (e.g., station or access point). Typically, the closer the transmitting device is to the targeted device, the less error there will be in the reception of the transmitted signal.

A cognitive radio is a wireless communication device that can adjust transmission or reception parameters to communicate efficiently to avoiding interference. This alteration of parameters can be based on the active monitoring of several factors in the external and internal radio environment, such as radio frequency spectrum, user behavior and network state.

When one or more of these communication devices is mobile, its transmit and receive characteristics can change with the motion of the device, as it moves closer or farther from a device it is communication with, and as the transmission environment changes due to the devices position with respect to reflecting members, interfering stations, noise sources, etc.

The limitations and disadvantages of conventional and traditional approaches will become apparent to one of ordinary skill in the art through comparison of such systems with the present invention.

The present invention is directed to apparatus and methods of operation that are further described in the following Brief Description of the Drawings, the Detailed Description of the Invention, and the claims.

Each antenna can be a fixed antenna, a single-input single-output (SISO) antenna, a multi-input multi-output (MIMO) antenna, a diversity antenna system, an antenna array that allows the beam shape, gain, polarization or other antenna parameters to be controlled or other antenna configuration. In addition, IC 50 includes input/output module 71 that includes the appropriate interfaces, drivers, encoders and decoders for communicating via the wireline connection 28 via wireline port 64, an optional memory interface for communicating with off-chip memory 54, a codec for encoding voice signals from microphone 60 into digital voice signals, a keypad/keyboard interface for generating data from keypad/keyboard 58 in response to the actions of a user, a display driver for driving display 56, such as by rendering a color video signal, text, graphics, or other display data, and an audio driver such as an audio amplifier for driving speaker 62 and one or more other interfaces, such as for interfacing with the camera 76 or the other peripheral devices.

In operation, the RF transceivers 73 . . . 73′ generate outbound RF signals from outbound data and generate inbound data from inbound RF signals to communicate with a plurality of networks, such as networks 6, 8, 107 and 111, etc. Configuration controller 221 configures one or more of the transceivers 73 . . . 73′, the antennas 72 . . . 72′ and the power management unit 95 to conform to channel conditions, the particular transmission requirements of data being sent and received by the transceivers 73 . . . 73′ in order to conserve power, reduce interference, and to communicate more efficiently with one or more networks or remote devices.

Power management circuit 95 can operate from one or more batteries, line power, an inductive power received from a remote device, a piezoelectric source that generates power in response to motion of the integrated circuit and/or from other power sources, not shown. In particular, power management module 95 can selectively supply power supply signals of different voltages, currents or current limits or with adjustable voltages, currents or current limits in response to control signals received from configuration controller. While shown as an off-chip module, PMU 95 can be alternatively implemented as an on-chip circuit.

In addition, IC 50 may include an location generation module 48 that generates location or motion parameters based on the location or motion of the device such as a longitude, latitude, altitude, address, velocity, velocity vector, acceleration (including deceleration), and/or other location or motion parameter.

Such a processing device, for instance, processing module 225, may be a microprocessor, micro-controller, digital signal processor, microcomputer, central processing unit, field programmable gate array, programmable logic device, state machine, logic circuitry, analog circuitry, digital circuitry, and/or any device that manipulates signals (analog and/or digital) based on operational instructions. The associated memory may be a single memory device or a plurality of memory devices that are either on-chip or off-chip such as memory 54. Such a memory device may be a read-only memory, random access memory, volatile memory, non-volatile memory, static memory, dynamic memory, flash memory, and/or any device that stores digital information. Note that when the IC 50 implements one or more of its functions via a state machine, analog circuitry, digital circuitry, and/or logic circuitry, the associated memory storing the corresponding operational instructions for this circuitry is embedded with the circuitry comprising the state machine, analog circuitry, digital circuitry, and/or logic circuitry.

Also note that while certain modules of communication device 125 are shown to be included on IC 50 while others are not, IC 50 is shown for illustrative purposes and may include more or less of the modules of communication device 125, depending on the particular implementation. Further, communication device 125 can include additional modules or fewer modules than those specifically shown. In operation, the IC 50 executes operational instructions that implement one or more of the applications (real-time or non-real-time) attributed to communication devices 125 as discussed above and in conjunction with FIGS. 1-3.

FIG. 5 is a schematic block diagram of an embodiment of RF transceiver 123, such as transceiver 73 or 73′, in accordance with the present invention. The RF transceiver 123 includes an RF transmitter 129, and an RF receiver 127. The RF receiver 127 includes a RF front end 140, a down conversion module 142 and a receiver baseband processing module 144 that operate under the control of control signals 141. The RF transmitter 129 includes a transmitter baseband processing module 146, an up conversion module 148, and a radio transmitter front-end 150 that also operate under control of control signals 141.

As shown, the receiver and transmitter are each coupled to an antenna 171 and a diplexer (duplexer) 177, such as antenna interface 72 or 74, that converts the transmit signal 155 to produce outbound RF signal 170 and converts the inbound signal 152 to produce received signal 153. Alternatively, a transmit/receive switch can be used in place of diplexer 177. While a single antenna is represented, the receiver and transmitter may share a multiple antenna structure that includes two or more antennas. In another embodiment, the receiver and transmitter may share a multiple input multiple output (MIMO) antenna structure, diversity antenna structure, phased array or other controllable antenna structure that includes a plurality of antennas. Each of these antennas may be fixed, programmable, and antenna array or other antenna configuration.

In operation, the transmitter receives outbound data 162 from other portions of its a host device, such as a communication application executed by processing module 225 or other source via the transmitter processing module 146. The transmitter processing module 146 processes the outbound data 162 in accordance with a particular wireless communication standard (e.g., IEEE 802.11, Bluetooth, RFID, GSM, CDMA, et cetera) to produce baseband signal that may either a true baseband signal with no frequency offset or be a low intermediate frequency (IF) transmit (TX) signals that contains outbound data 162. The baseband or low IF TX signals 164 may be digital baseband signals (e.g., have a zero IF) or digital low IF signals, where the low IF typically will be in a frequency range of one hundred kilohertz to a few megahertz. Note that the processing performed by the transmitter processing module 146 can include, but is not limited to, scrambling, encoding, puncturing, mapping, modulation, and/or digital baseband to IF conversion.

The up conversion module 148 includes a digital-to-analog conversion (DAC) module, a filtering and/or gain module, and a mixing section. The DAC module converts the baseband or low IF TX signals 164 from the digital domain to the analog domain. The filtering and/or gain module filters and/or adjusts the gain of the analog signals prior to providing it to the mixing section. The mixing section converts the analog baseband or low IF signals into up-converted signals 166 based on a transmitter local oscillation.

The radio transmitter front end 150 includes a power amplifier and may also include a transmit filter module. The power amplifier amplifies the up-converted signals 166 to produce outbound RF signals 170, which may be filtered by the transmitter filter module, if included. The antenna structure transmits the outbound RF signals 170 to a targeted device such as a RF tag, base station, an access point and/or another wireless communication device via an antenna interface 171 coupled to an antenna that provides impedance matching and optional bandpass filtration.

The receiver receives inbound RF signals 152 via the antenna and off-chip antenna interface 171 that operates to process the inbound RF signal 152 into received signal 153 for the receiver front-end 140. In general, antenna interface 171 provides impedance matching of antenna to the RF front-end 140, optional bandpass filtration of the inbound RF signal 152 and optionally controls the configuration of the antenna in response to one or more control signals 141 generated by processing module 225.

The down conversion module 142 includes a mixing section, an analog to digital conversion (ADC) module, and may also include a filtering and/or gain module. The mixing section converts the desired RF signal 154 into a down converted signal 156 that is based on a receiver local oscillation, such as an analog baseband or low IF signal. The ADC module converts the analog baseband or low IF signal into a digital baseband or low IF signal. The filtering and/or gain module high pass and/or low pass filters the digital baseband or low IF signal to produce a baseband or low IF signal 156. Note that the ordering of the ADC module and filtering and/or gain module may be switched, such that the filtering and/or gain module is an analog module.

The receiver processing module 144 processes the baseband or low IF signal 156 in accordance with a particular wireless communication standard (e.g., IEEE 802.11, Bluetooth, RFID, GSM, CDMA, et cetera) to produce inbound data 160. The processing performed by the receiver processing module 144 includes, but is not limited to, digital intermediate frequency to baseband conversion, demodulation, demapping, depuncturing, decoding, and/or descrambling.

Further, configuration controller 221 generates one or more control signals 141 to configure or adapt the RF transceiver 123. In operation, configuration controller 221 generates control signals 141 to modify the transmit and/or receiver parameters of the RF transceiver 125 such as protocol parameters, data rates, modulation types, channel utilization methods, and other data parameters used by receiver processing module 144 and transmitter processing module 146, frequency bands, channels and bandwidths, filter settings, gains, power levels, ADC and DAC parameters, and other parameters used by RF front-end 140, radio transmitter front-end 150, down conversion module 142 and up conversion module 148, as well as antenna configurations used by antenna interface 171 to set the beam pattern, gain, polarization or other antenna configuration of the antenna.

In an embodiment of the present invention, the configuration controller receives channel data 143 from RF front end that indicates the receive conditions of the channel such as a receive signal strength, a signal to noise ratio, a signal to noise and interference ratio, and/or an automatic gain control signal or other data that indicates the current performance of the channel. In addition or in the alternative, configuration controller 221 can receive channel data 145 from receiver processing module 144. The channel data 145 can include a bit error rate, and/or a packet error rate that further indicates current channel conditions. Further, configuration controller 221 can receive requirements data corresponding to the stream of inbound data, wherein the requirements data includes a quality of service, a signal latency limit, and a signal content, for instance a signal type such as a real-time MPEG2 video stream, a real-time audio stream, a non-real-time data file, etc.

The configuration controller 221, receiver processing module 144 and transmitter processing module 146 can each be implemented with a dedicated or shared processing device. Such a processing device, for instance may be a microprocessor, micro-controller, digital signal processor, microcomputer, central processing unit, field programmable gate array, programmable logic device, state machine, logic circuitry, analog circuitry, digital circuitry, and/or any device that manipulates signals (analog and/or digital) based on operational instructions. The associated memory may be a single memory device or a plurality of memory devices that are either on-chip or off-chip. Such a memory device may be a read-only memory, random access memory, volatile memory, non-volatile memory, static memory, dynamic memory, flash memory, and/or any device that stores digital information. Note that when configuration controller 221, receiver processing module 144 and transmitter processing module 146 implement one or more of their functions via a state machine, analog circuitry, digital circuitry, and/or logic circuitry, the associated memory storing the corresponding operational instructions for this circuitry is embedded with the circuitry comprising the state machine, analog circuitry, digital circuitry, and/or logic circuitry.

In an embodiment of the present invention, configuration controller 221 includes a lookup table that generates control signals 141, based on the requirements data 223 and channel data 143 and 145. The control signals 141 can be analog signals, digital signals, discrete-time signals of other signals that control the modules of RF transceiver 123 to adapt to communication based on channel data 143 and 145 and requirements data 223. In particular, control signal 141 can be a plurality of individual signals or a single multidimensional signal that independently control the various modules of RF transceiver 123, that adjusts, adapts, controls or otherwise configures the operation of other similar transceivers 123 and the power management unit 95. Further details regarding particular conditions for generating control signals 141 will be discussed in conjunction with FIGS. 6-20 that follow.

FIG. 6 is a schematic block diagram of an embodiment of a transmitter processing module 146 in accordance with the present invention. In particular, transmitter processing module 146 processes outbound data in a plurality of transmitter stages to produce at least one baseband signal, such as baseband or low IF transmit signal 164. In the embodiment shown, these transmitter stages include scrambling stage 180, encoding stage 181, interleaving stage 182, mapping stage 183, and space/time coding stage 184. Transmitter processing module 146 further includes inverse FFT module 185, that can optionally be bypassed as well. In response to control signals 141, each of these stages can be individually and selectively bypassed by the multiplexers 186. In operation, the multiplexers 186 implement a switching matrix for selectively switching-in or bypassing each of the transmitter stages to place the transmitter processing module 146 in different configurations. Each of the transmitter stages can be individually powered via a dedicated power supply signal from power management unit 95. In this fashion, transmitter stages not in use can be powered down to conserve power.

In addition, each of the transmitter stages 180-184 can also be individually configured. In this fashion, control signal 141 can select from one of a plurality of scrambling methods, or use different scrambling seeds or encryption keys, can select from one of a plurality of encoding techniques, can select from one of a plurality of interleaving configurations, can select from one of a plurality of mappings and one of a plurality of space/time codings.

By selectively bypassing one or more transmitter stages and/or configuring each of these stages, transmitter processing module 146 can be configured in response to control signal 141 to one of a plurality of modulation modes such as a minimum shift keying mode, a binary phase shift keying mode, a quadrature phase shift keying mode, a quadrature amplitude modulation module, and a frequency shift keying mode, and to a selected one of a plurality of channel utilization modes, such as a orthogonal frequency division multiplexing mode, a coded orthogonal frequency division multiplexing mode, a time division multiplexing mode, a frequency division multiplexing mode, a code division multiplexing mode and a spread spectrum mode.

While transmitter processing module 146 is shown to produce a single baseband or low IF transmit signal 164, multiple baseband or low IF transmit signals can be generated by one or more redundant paths for applications such as where transmitter processing module 146 is coupled to an RF transmitter section that itself is configurable to generate a plurality of RF signal for transmission by a plurality of antennas. In this embodiment, the transmitter processing module 146 can be configurable in response to the control signal 141 to a selected one of a plurality of antenna modes, such as a single input single output mode, a multi-input single output mode, a single input multi-output mode and a multi-input multi-output mode.

In this fashion, configuration controller 221 can configure the channel utilization, antenna mode for efficient throughput based on the channel conditions reflected by channel data 143 and 145 and further based on the requirements data 223. For example, when excellent channel conditions are observed with high received power and low interference, particular redundancies and channel compensating features can be reduced or bypassed altogether to simplify the generation of the baseband or low IF transmit signal, and or to reduce power by reducing processing speeds and/or by disabling bypassed transmit stages.

FIG. 7 is a schematic block diagram of an embodiment of a receiver processing module 144 in accordance with the present invention. In a complementary fashion to transmitter processing module processing module 146, receiver processing module 144 includes a plurality of receiver stages that can be individually configured and selectively bypassed in response to control signal 141 to produce a stream of inbound data 160. In particular, these stages include a descrambling stage 194, a decoding stage 193, a deinterleaving stage 192, a demapping stage 191, and a space/time decoding stage 190 as well as FFT stage 189 that also may be selectively bypassed, based on the particular implementation. Each of the receiver stages can be individually powered via a dedicated power supply signal from power management unit 95. In this fashion, receiver stages not in use can be powered down to conserve power.

In particular, an RF transmitter section is shown, such as radio transmitter front end 150 and up conversion module 148. The RF transmitter section generates one or more RF signals 224 from the at least one baseband signal, such as baseband or low IF transmit signal 164, that are coupled to antenna module 214, such as antenna 171. Antenna module 214 can include a plurality of antennas driven by the RF signals 224.
